I'm almost done my series of design patterns using PHP 5. Today's
pattern is the Strategy Pattern.

http://www.fluffycat.com/PHP-Design-Patterns/Strategy/

In the Stratedy Pattern a "family of algorythms" is used interchangably
by calling clients.

This is the second pattern in as many days as I've used my older work
with patterns in Java, and again I liked the old example when I first
looked at it, but now I wonder about it. In this example the context
is passed a parameter at instantiation, and the context then chooses a
concrete strategy which it hold on to for every time it needs a
strategy. This means that the calling client would need to call the
appropriate context. Not sure if this is the real intent here, might
have to revisit this one...
